How to read these numbers
Every price is the final bid of a public auction that actually closed with a sale, converted to euro at the exchange rate of that day and checked by a reviewer. Fixed-price sales, bundles and spare parts are left out.
Figures are averages of the recorded sales, so a model with few sales can swing from one year to the next: check the number of sales behind each figure. More on the method.
